Abstract
Die Erfindung betrifft eine Vorrichtung und ein Verfahren zur Herstellung von Hakenbefestigungselementen (71), umfassend ein drehbares Matrizenrad (60), das im Inneren mit einem Wasserkanal zur Kühlung mittels Wasserströmung und einer Anzahl von hakenförmigen Hohlräumen (61) ausgestattet ist, die an der Umfangsfläche vorgesehen sind, wobei sich an beiden gegenüberliegenden Seiten des Matrizenrades jeweils eine Extrusionsvorrichtung (80) und eine Kühleinrichtung (90) befinden. Die Extrusionseinrichtung (80) wird dazu verwendet, Formmasse (70) wie geschmolzenen Kunststoff über einen Satz von oberen und unteren Düsenabschnitten (81, 82) zu extrudieren, die sich nahe der Umfangsfläche des Matrizenrades befinden und einstellbar zurück und vor zusammen mit der Extrusionsvorrichtung bewegt werden, um die Dicke der Basisabschnitte (73) von hierdurch zu formenden Hakenelementen (71) zu bestimmen. Die aus der Extrusionsvorrichtung (80) extrudierte Formmasse (70) wird daher genau in die hakenförmigen Hohlräume (61) des Matrizenrades (60) eingefüllt. Erfindungsgemäß kann so eine ausreichende Schmelztemperatur für ein direktes und vollständiges Einspritzen in die hakenförmigen Hohlräume (61) beibehalten werden, bevor die Formmasse geeignet mittels der Kühleinrichtung (90) gekühlt und verfestigt wird und gleichmäßig aus den hakenförmigen Hohlräumen (61) in der endgültigen Formgestalt von Hakenelementen entfernt wird, womit die Auusfallrate wirksam verringert wird.The invention relates to an apparatus and method for making hook fasteners (71) comprising a rotatable die wheel (60) internally provided with a water flow cooling water channel and a plurality of hook shaped cavities (61) on the peripheral surface are provided, wherein on both opposite sides of the die wheel in each case an extrusion device (80) and a cooling device (90) are located. The extruder (80) is used to extrude molding material (70) such as molten plastic over a set of upper and lower nozzle sections (81, 82) located near the peripheral surface of the die wheel and adjustably moved back and forth along with the extrusion device to determine the thickness of the base portions (73) of hook members (71) to be formed therethrough. The extruded from the extrusion device (80) molding compound (70) is therefore filled exactly in the hook-shaped cavities (61) of the die wheel (60). Thus, according to the invention, a sufficient melting temperature for direct and complete injection into the hook-shaped cavities (61) can be maintained before the molding compound is cooled and solidified suitably by the cooling device (90) and evenly from the hook-shaped cavities (61) in the final shape of FIG Hook elements is removed, whereby the fall rate is effectively reduced.
Description
Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung von Hakenbefestigungselementen, umfassend ein drehbares Preßwerkzeug- bzw. Matrizenrad, das im Inneren mit einem Wasserkanal zur Kühlung mittels Wasserströmung ausgestattet ist, und eine Anzahl von hakenförmigen Hohlräumen, die an der Umfangsfläche vorgesehen sind, wobei sich an beiden gegenüberliegenden Seiten des Formpreßwerkzeugrades jeweils eine Extrusionsvorrichtung und eine Kühleinrichtung befinden und die Extrusionsvorrichtung Formmasse wie geschmolzenen Kunststoff direkt in die hakenförmigen Hohlräume des Matrizenrades ohne Aufbringen eines weiteren Druckrades auf diesen extrudieren kann. Die Verwendung eines Druckrades bei herkömmlichen Formungsverfahren wird so in wirtschaftlicher Weise fortgelassen und es wird erleichtert, daß die Formmasse eine Schmelztemperatur beibehält, die ausreichend ist für ein direktes und vollständiges Einspritzen in die hakenförmigen Hohlräume, bevor sie sich abkühlt und zu geformten Hakenelementen verfestigt für eine gleichmäßige Entfernung hieraus, so daß die Ausfallrate wirksam reduziert werden kann.The The present invention relates to a process for the preparation of Hook fastening elements comprising a rotatable press tool or die wheel, which in the interior with a water channel for cooling by means water flow is equipped, and a number of hook-shaped cavities, the the peripheral surface are provided, wherein on both opposite sides of the Formpreßwerkzeugrades each an extrusion device and a cooling device are located and the extrusion device molding compound such as molten plastic directly in the hook-shaped Cavities of Die wheel without applying another pressure wheel on this can extrude. The use of a pressure wheel in conventional Forming process is thus omitted economically and it is relieved that the Molding compound maintains a melting temperature sufficient for a direct and complete Injection into the hook-shaped cavities before it cools down and solidified into shaped hook elements for uniform removal from this, so that the Failure rate can be effectively reduced.

Bei
dem zweiten bekannten Verfahren zur Herstellung von Hakenbefestigungselementen
gibt es einige Nachteile. Erstens werden die geformten Hakenelemente
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, ein Verfahren zur Herstellung von Hakenbefestigungselementen zu schaffen, bei dem die hakenförmigen Hohlräume vollständig gefüllt und die Formmasse gleichmäßig aus den Hohlräumen entfernt werden kann, so daß Hakenelemente mit hoher Qualität und glatter Oberfläche bei herabgesetzten Herstellungskosten gefertigt werden können.Of the The present invention is therefore based on the object, a method for creating hook fasteners to create the hook-shaped cavities Completely filled and the molding compound evenly removed from the cavities can be, so that hook elements with high quality and smooth surface can be manufactured at reduced production costs.
Diese Aufgabe ist erfindungsgemäß bei einem Verfahren mit den Markmalen des Anspruchs 1 gelöst. Vorteilhafte Weiterbildungen des erfindungsgemäßen Verfahrens sind Gegenstand der Unteransprüche. Weiter ist durch die Erfindung eine Vorrichtung mit den Merkmalen des Anspruchs 4 geschaffen worden, mit der das erfeindungsgemäße Verfahren ausgeführt werden kann.These Task is according to the invention in a Method solved with the Markmalen of claim 1. Advantageous developments the method according to the invention are the subject of the dependent claims. Next is a device with the features by the invention of claim 4, with which the method according to the invention is carried out can.
Gemäß der Erfindung wird somit ein Verfahren zur Herstellung von Hakenbefestigungselementen zur Verfügung gestellt, umfassend eine Extrusionsvorrichtung, die so angeordnet ist, daß sie einem drehbaren Matrizenrad gegenüberliegt, das mit einem Wasserströmungskanal im Inneren versehen ist und an dessen anderer Seite sich eine Kühleinrichtung gegenüberliegend der Extrusionsvorrichtung zur unmittelbaren Abkühlung befindet, wobei Formmasse wie geschmolzener Kunststoff direkt in die hakenförmigen Hohlräume eingefüllt wird, die sich an der Umfangsfläche des Matrizenrades befinden und geeignet durch die oben erwähnte Kühleinrichtung abgekühlt werden, ohne daß ein weiteres Druckrad darauf aufgebracht wird, womit in wirtschaftlicher Weise das Druckrad herkömmlicher Gießformverfahren fortgelassen wird und die Herstellkosten verringert sind, so daß eine vereinfachte Pressformvorrichtung mit minimalem Raumbedarf zur Verfügung gestellt wird.According to the invention Thus, a method for the production of hook fasteners to disposal comprising an extrusion device arranged so arranged is, that you a rotatable die wheel opposite, which with a water flow channel is provided inside and on the other side is a cooling device opposite the extrusion device for immediate cooling, wherein molding composition how molten plastic is poured directly into the hook-shaped cavities, which are on the peripheral surface of the die wheel and suitable by the above-mentioned cooling device chilled be without one further pressure wheel is applied to it, bringing in economic Make the print wheel more conventional cast molding is omitted and the manufacturing costs are reduced, so that a simplified Press molding device provided with minimal space requirement becomes.
Zweitens wird bei einem Verfahren zur Herstellung von Haken elementen gemäß der Erfindung die Formmasse, die aus der Extrusionsvorrichtung extrudiert wird, genau mit der Umfangsfläche des Matrizenrades und dessen hakenförmigen Hohlräumen in Kontakt gebracht, was das Beibehalten einer ausreichenden Schmelztemperatur der extrudierten Formmasse für ein direktes und vollständiges Füllen in die hakenförmigen Hohlräume unterstützen kann. Nach geeigneter Kühlung und Härten mittels der Kühlvorrichtung wird die in die hakenförmigen Hohlräume eingefüllte Formmasse gleichmäßig in der endgültigen geformten Gestalt entfernt, ohne daß irgendwelche Reste darin bleiben, so daß hochqualitative Hakenelemente mit vollständigen hakenförmigen Vorsprüngen zur Verfügung gestellt werden und die Ausfallrate wirksam herabgesetzt wird.Secondly is in a process for the preparation of hook elements according to the invention the Molding material extruded from the extrusion device, exactly with the peripheral surface the die wheel and its hook-shaped cavities in Contacting, resulting in maintaining a sufficient melting temperature the extruded molding compound for a direct and complete Fill in the hook-shaped cavities support can.
